WC2HX-P230BLUETOOTH SPEAKER

Note: Under Industry Canada regulations, this radio transmitter may only operate using an antenna of a type and maximum (or lesser) gain approved for the transmitter by Industry Canada. To reduce potential radio interference to other users, the antenna type and its gain should be so chosen that the equivalent isotropically radiated power (e.i.r.p.) is not more than that necessary for successful communication.

Circuit Description: The Bluetooth Speaker includes below main components：IC2 (HX6001), U3 (HT6809), U2 (LM358), U1(bluetooth module), USB2(mini USB socket), JK1(headphone jack), K1(power switch), S1(button), S2(button), S3(button), LED1(light diode), LED3(light diode)，BAT(Li-ion battery). Bluetooth circuit: The IC3 and L8, C14, C2, C25 constitute a 3.3Vvoltage supply U1 circuit (utilizing a 12MHz oscillator), which will receive and decode the audio signal and then via the C4, C6 input to U2, after U2 magnification and high-pass filter output to U3 power amplifier, and then by U3 power amplifier output to the speaker.Through the S1, S2 control U3, make U1 I/O, PIO4 control IC3 increase volume; AIO3 control U3 reduced volume.S3 control U1, make its control music play/pause. LED3 for bluetooth indicator. AUX audio circuit: JK1 for external audio input port AUX, audio through input to the U2 C1 high-pass filter, and then by U3 power amplifier output to the speaker. Charging circuit explanation: USB2 mini USB socket of the input DC5V supply IC2 first constant current 310 mA, again constant pressure to lithium battery charging 4.2 V. LED1 for charging indicator .
